It often has a concentration about 1/20 that of tartaric acid.

So it is a measure of how high the acid concentration is.

Urocanic acid concentrations can be up to five times greater in the foot than any other part of the human body.

The bases also help reduce the overall acid concentration inside the enclosed space.

There is linear relationship between the current generated and the concentration of sulfuric acid.

Moreover, in one increased concentrations of docosahexaenoic acid (C22:6n3) were also found.

"His condition would have been missed if they hadn't measured the pristanic acid concentration."

Depending on the acid concentration, temperature and the reducing agent involved, the end products can be variable.

There is also evidence that increased concentrations of quinolinic acid can play a role in adolescent depression.

These increased concentrations of quinolinic acid could lead to neurotoxicity.
